Application filed February 24, 1887. Serial No. 228,697. (No model.)

To all whom it may concern.-

Be it known that I, EM'ERY M. HAMILTON, of New York, in the county ofNew York, and in State of New York, have invented certain new and usefulImprovements in Apparatus for Recording Measurements of Time, Space, orQuantity; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, in which Figure 1 is a perspective view of my device asarranged for use. Fig. 2'is a plan view of the upper side of the base,the inking-ribbon being broken away and the platens removed to show theprinting-dies. Fig. 3 is a perspective view of a portion of thetimetrain and the die-operating connections separated from the otherparts of the device. Fig. 4 is a vertical section of the device upon aline passing through the axes of the dial and printing-dies. Figs. 5 and6 are cross-sections of the platens upon lines a: a: and y y,respectively, of Fig. 4. Fig. 7 is a plan view of a ticket which hasbeen stamped at .the commencement of an interval of time, and Fig. 8 isa like view of the same when stamped at the close of such interval.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to enable the value of intervals of timeat any predetermined rate to be computed and recorded byautomatically-chan gin g mechanism; andto this end my said inventionconsists in a device constructed and adapted for use in the manner andfor the purpose substantially as hereinafter specified. I

In the carrying of my invention into practice I employ a rectangularmetal base-plate A, which is secured upon a wooden block B, thatcorresponds therewith in general shape, and within its upper side isprovided with a recess 1) for the reception of some of the operativemechanism.

TVithin the front portion of the base plate A, at its transverse center,is formed a circucular opening a, that is glazed at its upper side andreceives and contains the dial 0 and hands 0 and c of a time mechanism,the train D for which is arranged beneath in the reeess I).

In rear of the dial-opening a, and in a line with the same, there isformed in the baseplate A a circular recess a, that generally has adepth about equal to one-half the thickness 5 5 of the latter and at itscenter a extends entirely through said plate. TVithin said recess isplaced a die E, which has its upper face substantially flush with theface of said baseplate, and upon the same is provided with a concentricseries of raised numerals e, that are placed at equidistant pointsaround the circle, and by tens extend progressively from 0 to 90, thearrangement being such as to divide said circle into one hundred equalparts, of which each successive tenth division is numbered. Said die isprovided with a hub e, that extends through the opening a and engageswith the hub f of a wheel F, which wheel is connected with thetime-train D, so as to have an entire revolution during anypredetermined period of time.

Within the line of numerals e of the die E, and in juxtaposition withthe zero-numeral 0, is a raised arrow-head e and inside of the 7 5latter is formed a circular recess 6 that receives and contains a seconddie G. Said die G is provided with a central hub g, that ex tendsdownward through an axial opening in the hub e and engages with an arborh, which is secured within a toothed wheel H, and the latter is soconnected with the timetrain as to cause said die Gto make one completerevolution while said die E is revolving ten times. Upon the upper faceof said die G is a concentric series of raised numerals g and g,whichare equidistant from each other, are ten in number, and extend inconsecutive order from 1 to 0. At apoint opposite to and outside of thecharacter 0 a raised arrow-head g is formed upon said die.

Secured to the end of the base A, adjacent to the dies E and G, is abracket-arm I,which from thence extends upward and thence horizontallyinward, and at a point directly over 5 said dies carries a cylindricalsleeve or barrel K, that is arranged with its axis in a line with theaxes of the latter.

WVithin the barrel K is loosely fitted a hollow sleeve L, which extendsfrom the upper end downward below the lower end of the same, and uponits lower projecting end has secured or formed a head Z, that has suchdiameter and thickness as to enable it when moved downward upon the diesE and G to cover the space between the series of numerals e and g and toimpinge upon the arrowheads 6 and g Said sleeve is adapted to be moveddownward by means of a rod Z, that is secured horizontally within itsupper part and extends outward through a verticallyelongated slot i inthe barrel I, and is provided upon its outer end with a knob Ziwhile itis returned to its upper normal position, when released, by means of aspiral spring M, which extends between said rod Z and a screw i, thatpasses horizontally through the lower end of said barrel and intoaverticallyelongated slot Z in said sleeve.

Fitted loosely within the sleeve L is a second sleeve N, which upon itsupper projecting end has secured a knob 02, and upon its lower end a,which normally is flush with the head 1, has secured an annular head orenlargement 72?, that is provided with connecting-lugs 15, which projectradially inward through corresponding vertically-elongated slots Z and Zin said sleeve L. The lower end n of said inner sleeve N has suchdiameter and thickness that when pressed down upon the die G it willcover the annular series of numerals g, while the enlargement n has suchdimensions as to cause it to simultaneously cover the series of numeralse of the die E. The inner sleeve N is normally held with a yieldingpressure at the upper limit of its motion by means of a spiral spring 0,which has less strength than the springM, and is placed between the knob12. and the operating-rod Z of the sleeve L.

An inked ribbon P, having its ends wound around suitable spools beneaththe base-plate A, and from thence passing upward through slots a and ain said base-plate and across dies E and G, and a guide-strip Q, securedupon and extending across said base-plate at one side of the dial anddie-recesses, completes the device, the operation of which, inconnection with the time and pay of an operative, is as follows, viz:The numerals upon the die E represent cents, and those upon the die Grepresent dollars, and said die E is arranged to make one entirerevolution in the time required for earning one dollar atthepredetermined rate, which time, for the purpose of illustration, isfixed at five hours, or twenty cents per hour. Suppose that at 8 a. m.an operative reports for work. A ticket R, bearing his name and thedate, is placed in position over the dies and each of the stamping-headsor platens is pressed downward until the ticket has impressed upon itslower face, through the medium of the inked ribbon, a facsimile of thenumerals of each die with the arrow-heads of each pointing to zero, asshown in Fig. 7. At 4.30 p. in. the operative quits work and presentshis ticket for stamping, when said ticket is placed in the preciseposition it before occupied and the central platen moved downward, so asto cause the arrow-heads alone to be impressed thereon; but as in themeantime the dies have been steadily revolving their change of positionsince 8 a. in. will cause the last impression of the outer arrow-head tocome opposite to the number of the cents-die and the impression of theinner arrow-head to occupy a position between the numbers 1 and 2 of thedollars-die, as seen in Fig. 8, so that said ticket would show that theoperative had earned and was entitled to one dollar and seventy centsfor the eight and one-half hours of his work.

It will be obvious that the values reprew sented by the figures orcharacters of the dies and the relative or separate rates at which theyrevolve may be varied at will without departing from the spirit of myinvention.

Having thus described my invention, what I claim is A machine formeasuring and recording intervals of time in which are combined tworotatable concentrically-arranged printingdies, each of which carries anannular series of numerals-type, and a pointer-type that is injuxtaposition with the zero-type of the series, said pointer-types beingarranged, respectively, one within the line of its annular series ofnumerals-type an d the other outside of the line of its annular seriesof types, a time-train that is adapted to rotate the dies at uniform butrelatively dilferent velocities, a platen that is adapted to press aticket simultaneously upon the numerals-type of both series, and anindependently-operative second platen that is adapted to press saidticket simultaneously upon the pointer-type of both dies, substantiallyas and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this14th day of February, 1887.

EMERY M. HAMILTON.
